A Letter From Bill Putnam, Jr.

Congratulations on your new UAFX pedal. We know that buying any new piece of gear requires an investment of time and money, and we aim to make your investment pay off!

At UA, we are dedicated to the idea of building “instant classics” — the type of music and audio gear that delivers album-worthy sounds to inspire you for decades.

UAFX pedals represent more than 20 years of research into vintage analog effects, coupled with next-generation digital engineering and rock-solid reliability.

Please let us know how we’re doing. Feel free to reach out to us via our website, and via our social media channels.

Thank you for your support, and enjoy your sonic exploration!

Orion Tape Echo Overview

Orion Tape Echo gives you the magical, hazy delay effects of vintage ’70s Maestro Echoplex EP-III tape delays, in a compact pedal.* Thanks to the same award-winning algorithms from our Starlight Echo Station, Orion gives you the rich, three-dimensional effects of a thoroughly emulated vintage tape echo — for tones that outshine all other compact tape delay pedals. Choose from three sonically distinct versions of the EP-III with Mint, Worn, and Old machine types for color and vibe, and tweak the Wonk control for subtle-to-eccentric modulated repeats and funky tape splice textures. 

Key Features

  • Authentic emulation of a vintage Maestro Echoplex EP-III tape echo in a compact stompbox*
  • True or trails bypass and switchable preamp
  • Perfectly captured analog preamp for fat, boosted tones and effects
  • Selectable Mint, Worn, and Old tape types for added color and texture
  • Wonk control for modulated repeats and vibey tape splice sounds

*All trademarks are property of their respective owners and used only to represent the effects modeled as part of Orion Tape Echo.

Orion Controls

The following controls are available on Orion.


Sets the tape echo rate, from 80-700 milliseconds. Because Orion is a tape-based delay, the echo pitches vary as you adjust this control.


Adjusts the amount of delayed signal mixed with the clean signal. When the mix control is fully clockwise, the delay is 100% wet.


Use this switch to select the tape character for Orion’s delay repeats: Mint, Worn, or Old. 


Tape Details
Mint A new old stock “closet classic” machine with new old stock tape and snappy compander compression circuit on the record head.
Worn Gently used tape, on a medium well-maintained early ‘70s machine with no compander circuit.
Old Mid ‘70s unit, less well-maintained, with very worn tape and plenty of warbly, chorus-like repeats.



Feedback controls the number of delay repeats. At high feedback settings, delay repeats begin to self-oscillate. To stop self-oscillation or indefinite feedback, reduce the Feedback amount. 

Note: Bypassing the pedal does not stop self-oscillation. In True Bypass mode, self-oscillation continues while the pedal is bypassed and returns when the effect is re-enabled. In Trail Bypass mode, self-oscillating repeats continue when the pedal is bypassed. 


The Wonk control adjusts tape wow, flutter, and modulation. Wonk interacts with the Tape Age switch, with the control having more impact on the sound with the Old and Worn tape settings.

Rec Level

The Rec Level control adjusts how hot the input signal is recorded to the tape. At higher levels, the tape will saturate and distort.

Bypass Mode

You can switch between Trails or True bypass modes using the slider switch on the back of the pedal. 

  • Trails - Echoes play out after the pedal is bypassed. The pedal’s output is buffered when the effect is on and off. 

Trails bypass minimizes high frequency loss from long cable runs, and preserves your tone when you have multiple pedals in series. 

  • True - Echoes are cut off immediately when the pedal is bypassed. The pedal signal is true bypass when the effect is off.

Preamp Mode

You can enable the EP-III preamp on the dry signal using the slider switch on the back of the pedal. The EP-III preamp has a warmer, fatter tone with less high end.

Note: The preamp is always active on the delayed signal.

  • On: The preamp is on the dry signal when the effect is on, or in Trails bypass mode. 
  • Off: The preamp is not on the dry signal. 

The preamp effect is enabled on the dry signal differently depending on whether True Bypass or Trails Bypass is enabled, and whether the pedal is on or bypassed. See the following chart.


Trails  Preamp Preamp sound LED color
True Off Preamp is not on dry signal Green
Trails Off Preamp is not on dry signal Purple
True On Preamp is on dry signal when pedal is on Orange
Trails On Preamp is always on dry signal, whether pedal is on or bypassed Red



The footswitch toggles the effect on/off. The LED lights to indicate when the effect is active. The LED color changes to indicate the pedal settings for True and Trails bypass and the Preamp setting, as shown in the table above.
